I, too, hear the "clicky noises," but using cw with PTT (rather than QSK). I use 400 Hz filter, AGC-F, and an external keyer.
The cw Monitor audio level could be increased to match the receiver audio capability. I am using 8 Ohm headphones, which may be part of the problem (the manual recommends 16-Ohm minimum impedance for headphones). I am using the Heil FS-2 foot switch which keys the Alpha 99 amp PTT relay a fraction of a second sooner than the K3. I had planned to key the amp from the K3 KEY OUT jack. But when using the latter configuration, I can hear the amp vacuum relay keying as if in QSK. This can be distracting when one wants a steady keying condition to the amp from the K3. 73, Norm - W1MO K3 #426 (AGC mod done at factory) _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
